"Floating" drivers are required for high side switches, e.g. industry standard bootstrap drivers, alternatively isolated drivers with separate supply or transformer based circuits.

It's a series topic at Edaboard.
 

LTC has a new MOSFET-quad driver out, meant for
offline (low frequency) applications. Meant to solve
exactly the topic problem.
